Stylized Double Integrals do not work (on an iMac OS X 10.9.2) as outlined in (and tested within) the Virtual Book under "Integrate" for the following example.
\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(1\)]\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(x\)]Sin[x\ y] \[DifferentialD]y \[DifferentialD]x\)\)
However, if brackets are put between the integrals and the differential dy and dx as per the following code
\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(1\)]\(\((
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(x\)]Sin[x\ y] \[DifferentialD]y)\) \[DifferentialD]x\)\)
.....then the code executes properly.
Do the brackets have to be there? If not, why won't the unbracketed example work on my iMac? Also, any way to get stylized integrals to appear in this question?
